interface, so we can focus on a function to process a URL. As for the URL-to-function mapping, it is given to the web framework. Because it is easy to develop a web framework in Python, Python has hundreds of open-source web frameworks. Here we do not discuss the advantages and disadvantages of various web frameworks, directly choose a more popular web framework--flask to use. Writing a web App with

hash algorithm is unidirectional, meaning it can only hash the password, but cannot restore the password. But these algorithms are absolutely reliable, input the same content, then the content of the hash will be the same. Usually when registering or validating, the comparison is the result of the hash.User RegistrationIn this example, the client sends a POST request to the/api/users, and the body part of the request must be in JSON format and contains the username and password fields.Code impl

But how to handle HTTP requests is not a problem, but the question i

Request scheduling When the program receives a request from the client, the view function to process the request is found. To complete this task, flask finds the requested URL in the URL map of the program. A URL mapping is a correspondence between a URL and a view function. Flask generates mappings using the App.route adorner or the App.add_url_rule () in the form of a non adorner. You can use App.url_map
